- A new endpoint `/v1/agent/service/:service_id` which is a generic way to look up the service for a single instance. The primary value here is that it: - **supports hash-based blocking** and so; - **replaces `/agent/connect/proxy/:proxy_id`** as the mechanism the built-in proxy uses to read its config. - It's not proxy specific and so works for any service. - It has a temporary shim to call through to the existing endpoint to preserve current managed proxy config defaulting behaviour until that is removed entirely (tested). - The built-in proxy now uses the new endpoint exclusively for it's config - The built-in proxy now has a `-sidecar-for` flag that allows the service ID of the _target_ service to be specified, on the condition that there is exactly one "sidecar" proxy (that is one that has `Proxy.DestinationServiceID` set) for the service registered. - Several fixes for edge cases for SidecarService - A fix for `Alias` checks - when running locally they didn't update their state until some external thing updated the target. If the target service has no checks registered as below, then the alias never made it past critical. |

Consul API client
This package provides the api
package which attempts to
provide programmatic access to the full Consul API.
Currently, all of the Consul APIs included in version 0.6.0 are supported.
Documentation
The full documentation is available on Godoc
Usage
Below is an example of using the Consul client:
package main
import "github.com/hashicorp/consul/api"
import "fmt"
func main() {
// Get a new client
client, err := api.NewClient(api.DefaultConfig())
if err != nil {
panic(err)
}
// Get a handle to the KV API
kv := client.KV()
// PUT a new KV pair
p := &api.KVPair{Key: "REDIS_MAXCLIENTS", Value: []byte("1000")}
_, err = kv.Put(p, nil)
if err != nil {
panic(err)
}
// Lookup the pair
pair, _, err := kv.Get("REDIS_MAXCLIENTS", nil)
if err != nil {
panic(err)
}
fmt.Printf("KV: %v %s\n", pair.Key, pair.Value)
}
To run this example, start a Consul server:
consul agent -dev
Copy the code above into a file such as main.go
.
Install and run. You'll see a key (REDIS_MAXCLIENTS
) and value (1000
) printed.
$ go get
$ go run main.go
KV: REDIS_MAXCLIENTS 1000
After running the code, you can also view the values in the Consul UI on your local machine at http://localhost:8500/ui/dc1/kv
